Commercial radio for listening to P25 trunking? NOT INTERESTED IN NAS.

I have no words....🤣

Then don't waste our time by not saying them. If you can't be helpful, be gone. If you can't be polite, be somewhere else.

It is established that TX inhibit also functions as RX inhibit in a P25 system. (Moto radio, Phase 1, Phase II, or both?)

Only in so far as preventing registration on a P25 system also prevents the radio from passing traffic. This only applies to parking the radio on a talkgroup. It does not apply to parking the radio on a conventional channel and using Multi-System Talkgroup or Intelligent Priority scan type that includes talkgroups (aka "NAS").

But for "by the book" NAS scanning, DOES IT WORK ON PHASE I and on Phase II? in today's modernized systems? Yes or no?

If you're asking if a modern MSI radio will pass traffic for both Phase I (FDMA) and Phase II (TDMA) talkgroups of a P25 system when setup for so-called "NAS"...the answer is yes. It works just fine, provided of course that the ASTRO 25 Channel ID table (aka band plan) is filled out correctly. And of course if the radio is capable of TDMA, i.e. that only applies to the APX series.

Thank you. I very much appreciate the clarification, and particularly that you have addressed all the scenarios I asked about.

Now I'll have no excuse if I get it wrong in the future. No reason that I should. My memory is as good as it ever was, I'm not THAT old yet!!!

Wow, wild ride guys! I applaud your commitment to support!

And while we are being perfectly clear, an XG100P with the latest firmware (XLPR06T02) or anything even close to current, programmed with a copy of RPM14 purchased from Harris does require a system key. I think a lot of people here overlook this fact…

What about RPM14 not purchased from Harris? Would that make all Harris NAS radio owners criminals? Affiliate and you break some rules. Non affiliate you break some laws. Seems like there is no legal way around it.

I’m not here to be anyone’s moral compass, nor anyone’s lawyer. I’m simply pointing out that saying you need a system key isn’t incorrect. Just because you have a system key, doesn’t mean you have zero application for NAS. The two are not mutually exclusive.

simple just don't update the firmware, its like upgrading an XPR to 2.10 is it really necessary to box yourself in when there really is no improvements for the application its intended for

I mean, you’re right in theory, but a lot of people here are buying used and in most cases, you get what you get and obtaining a particular revision can be difficult. I will say that if you are a Harris dealer or priority techlink account holder, Harris is actually very flexible so far as allowing you to downgrade to a firmware that works for you (way more so than M), but RPM10 is no longer available from Harris so you are still going to have to find that somewhere else. Most people will be scrambling to find firmware that works with it, which is probably not difficult to find if you meet the right people, but that doesn’t make it any more legitimate.

As a hobbyist, I’m not saying you have to start out completely legit, but it’s something to work towards. I started with borrowed software and have since purchased my own copy of RPM/RPM2 from a dealer. I’ll admit that I do enjoy the idea of being as legit as possible, but I definitely recognize that it can be expensive!

There are several ways to skin this cat, but only one completely legit way and 99.99% of us do not have that option…

well lets be honest technically if you NAS in any form you aren't "legit" in the legal sense, now then we get into the issue of the casual hobbyist or some whacker in those terms.

as far as monitoring goes, the Unication really changed the game, if you think about it for the price point it is as close to operation and performance as a system radio as you can get, that's the 100% legitimate way to go, no affiliation or interference concerns

Keep on keeping on with exercising my itchy inhibit fingers

 

[MTS2000des]

That part.
I heart GenWatch. Love my triggers with SMTP traps. Always fun to login, add bogus/suspect ID to PM, activate, login to RCM, inhibit...wait for thread to appear here with "my radio turns on then off. What did I do?"

GW_SAM is a good thing

If you use that feature on a P25 trunking system, you will get a "NO COMMS" error and the radio won't receive anything.

My Moto's work fine with that. The Harris cludge is being provoice.

 

[merlin]

Hmm...that's the first I've heard about that. Seems like kind of an odd choice. It's almost like M thinks there'd never be a need to be able to listen to instructions (on how to defuse a bomb, for example....) while operating in a strict EMCON environment.....positively bizarre when you stop and think about it.

The big M and L3 never intended their radios be turned into scanners, but workarounds have fixed some of that.

OK then I'm going to ask the final questions just to be over and done with it, never to ask this again and to KNOW what I've been missing for some time.

It is established that TX inhibit also functions as RX inhibit in a P25 system. (Moto radio, Phase 1, Phase II, or both?)

But for "by the book" NAS scanning, DOES IT WORK ON PHASE I and on Phase II? in today's modernized systems? Yes or no?

I want to be totally clear on this. I don't want to be operating on out of date and currently inaccurate information.

I've been out of date. Bring me back into currency.

I have a Moto XTS5000 I scan our ICAWIN system with. It is Moto P25 phase 1. I hid the 16 site TGs with conventional scan. (above16) That alone can keep from affiliating, but also set the rotary switch to 'TX inhibit' as backup. I hear all the talk groups that are not encrypted but the voice could sound better.
I have an XTL5000 programmed the same way. It works the same from channel 1-16. The problem is the channel select doesn't stop there.
You go past that, and you are on site channels and will try to affiliate. Great caution with channel selection is needed.
My 'TX inhibit mod' kills the PA stage so hardwired not to transmit. Problem solved.
These radios do phase 1, only, nicely unless they need alignment but what I have does work well.
Cheers.
There is no phase 2 here so can't test my other radios.

 

[merlin]

I'm going to be blunt...this is the problem with a lot of your posts. You have little to no experience with modern subscribers and modern systems. You constantly bring up experiences with antiquated equipment, and you often don't understand the context of the discussion.

We are talking about modern MSI radios on modern P25 systems. ASTRO 25 (XTL/XTS) and APX series subscribers, and how they function on a P25 system. We're not talking about radios from the late 80s/early 90s, and we're not talking about 4.x 3600 systems.

So to yet again answer the question in no uncertain terms: A modern MSI subscriber will not pass traffic from a P25 system when tuned to a talkgroup unless it first registers and affiliates (two distinct processes, by the way, as they are often conflated to mean the same thing).

The best of my Know is the TX inhibit was for the purpose of being able to receive but not transmit in hazardous areas like blasting.

I use GenWatch more than I do Zonewatch. I just have GW customized to perfection and it gives me all the info I need at a glance. I can also remote into it via VPN from anywhere on my phone. Add in the JPS VIA app on my phone I can pretty much see and hear my system anywhere, anytime.

 

[IAmSixNine]

Bottom line, Unication G4 proven to work on these types of systems and i love my now 7 year old KNG2-P800.
Right tool for the job scenario.

Uninhibit it. That's how you fix that. How you do that -- well now, that is an entirely separate conversation.
